Part from my old hard, have less space costs 2x 2x more expensive, it can hurt. But once up and running, the SSD makes you immediately forget that pain. I timed several operations before and after the assembly of this Flash Disk, here are the results compared with my old hard-drive (Seagate Barracuda 7200.12 500GB // // SATA Rev. 3):
Starting Windows 7 Pro 64 (after cleaning and defragmentation): Hard Disk SSD // = 138 sec = 27 sec.
Antivirus scan in fast mode under Microsoft Security Essentials: Hard = ~ 7 min // SSD = 1 min 14 sec.
Antivirus scan in full mode on Microsoft Security Essentials: Hard = ~ 80 min SSD // = ~ 15 min.
Full scan of my system with Spybot 2.0.12 Free Edition: HDD = ~ 30 min // SSD = 5 min 29 sec.
Read Speed Max in Atto Disk Benchmark: HDD = 127.9Mo / s SSD // = 511.3Mo / s
Max write speed in Atto Disk Benchmark: HDD = 126.2Mo / s SSD // = 414.8Mo / s
These figures speak for themselves, I think it is useless to go further.
Liked: It comes with an adapter for mounting in a rack 3 "internal 1/2, and a small table (20cm) SATA 6Gbps certified.
I did not like: Nothing, except perhaps the more day for delivery of my order, because of a holiday Monday history; o)
